Description

La présente invention se rapporte à un mécanisme de transmission interposé entre un arbre menant et un arbre mené, particulièrement applicable aux constructions automobile, nautique et à d'autres usages industriels en général.The present invention relates to a transmission mechanism interposed between a driving shaft and a driven shaft, particularly applicable to automobile, nautical and other industrial uses in general.

Plus précisément, le mécanisme selon l'invention est destiné àservir d'embrayage entre un arbre menant et un arbre mené.More specifically, the mechanism according to the invention is intended to serve as a clutch between a driving shaft and a driven shaft.

Les embrayages classiques, spécialement ceux qui sont utilisés en construction automobile et nautique, présentent l'inconvénient d'être affectés de limitation lorsqu'on veut disposer, sur l'arbre de transmission mené, du couple moteur maximal de l'arbre mené, sans risque d'avarie.Conventional clutches, especially those used in automobile and nautical construction, have the disadvantage of being limited when one wants to have, on the driven transmission shaft, the maximum engine torque of the driven shaft, without risk of damage.

Le but de l'invention est de réaliser un mécanisme de transmission qui puisse être particulièrement utilisé comme embrayage et qui ne présente pas les limitations des embrayages classiques.The object of the invention is to provide a transmission mechanism which can be used particularly as a clutch and which does not have the limitations of conventional clutches.

Un autre but de l'invention est de réaliser un mécanisme de transmission qui puisse servir en outre de variateur de vitesse, de convertisseur de couple, de régulateur de vitesse et de ralentisseur.Another object of the invention is to provide a transmission mechanism which can also serve as a speed controller, torque converter, speed regulator and retarder.

Selon l'invention, le mécanisme d'accouplement pour transmission comprend un bâti support dans lequel sont montés, libres en rotation, deux demi-arbres indépendants et alignés, reliés entre eux par un ensemble intermédiaire de pignons planétaires et satellites, les satellites étant montés dans une cage qui est indépendante du bâti support et qui entoure les planétaires.According to the invention, the coupling mechanism for transmission comprises a support frame in which are mounted, free in rotation, two independent and aligned half-shafts, interconnected by an intermediate assembly of planetary gears and satellites, the satellites being mounted in a cage which is independent of the support frame and which surrounds the planets.

La cage qui entoure les planétaires et les satellites porte deux volants extérieurs qui sont coaxiaux aux demi-arbres, chacun de ces volants étant placé de l'un des côtés de la cage ou du support et étant traversé par les demi-arbres. En outre, les volants portent une série de bobines qui sont alimentées par l'intermédiaire d'un collecteur monté extérieurement sur la cage. Ainsi qu'on l'a indiqué, les volants sont traversés par les demi-arbres montés libres en rotation.The cage which surrounds the planets and the satellites carries two external flywheels which are coaxial with the half-shafts, each of these flywheels being placed on one of the sides of the cage or of the support and being crossed by the half trees. In addition, the flywheels carry a series of coils which are supplied via a collector mounted externally on the cage. As indicated, the flywheels are crossed by the half-shafts mounted to rotate freely.

Le mécanisme selon l'invention comprend en outre deux autres volants d'entraînement, en matière ferromagnétique, qui sont montés solidairement chacun sur l'un des demi-arbres, et dans des positions parallèles aux volants qui portent les bobines, et proches de ces volants.The mechanism according to the invention further comprises two other drive wheels, made of ferromagnetic material, which are each mounted integrally on one of the half-shafts, and in positions parallel to the flywheels which carry the coils, and close to these ruffles.

Sur le bâti support, sont montées des bobines de freinage qui sont placées en regard des volants d'entraînement. Le bâti porte également des bobines d'inversion de marche qui sont placées en regard des volants porteurs des bobines.Braking coils are mounted on the support frame, which are placed opposite the drive wheels. The frame also carries reversing reels which are placed opposite the flywheels carrying the reels.

D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de rélisation et en se référant aux dessins annexés, sur lesquels :

  • la figure 1 est une coupe diamétrale d'un mécanisme d'accouplement construit selon l'invention ?
  • la figure 2 est un détail du mécanisme de la figure 1.
Other characteristics and advantages of the invention will be better understood on reading the description which follows of an exemplary embodiment and with reference to the appended drawings, in which:
  • Figure 1 is a diametrical section of a coupling mechanism constructed according to the invention?
  • FIG. 2 is a detail of the mechanism of FIG. 1.

Comme on peut le voir sur la figure 1, le mécanisme d'accouplement comprend un bâti support 1 dans lequel sont montés, libres en rotation, et au moyen de roulements 2 et 3, deux demi-arbres 4 et 5 indépendants et alignés. Ces deux demi-arbres sont reliés entre eux par un ensemble de planétaires 6 et de satellites 7, logés dans une cage 8 qui est indépendante du carter 1. Chacun des planétaires 6 est solidaire de l'un des demi-arbres 4 et 5 tandis que les satellites 7 sont montés dans la cage 8.As can be seen in Figure 1, the coupling mechanism comprises a support frame 1 in which are mounted, free to rotate, and by means of bearings 2 and 3, two independent and aligned half-shafts 4 and 5. These two half-shafts are connected to each other by a set of planets 6 and satellites 7, housed in a cage 8 which is independent of the casing 1. Each of the planets 6 is integral with one of the half-shafts 4 and 5 while that the satellites 7 are mounted in the cage 8.

Cette cage porte en outre, monté extérieurement, un collecteur 9 destiné à prendre le courant sur les sur des balais 10'. La cage 8 porte en outre, montés extérieurement, deux volants 10 et 11 coaxiaux aux deux demi-arbres 4 et 5 et situés chacun d'un côté de cette cage, ces volants étant traversés par les demi-axes précités montés libres en rotation. Les volants 10 et 11 portent une série de bobines 12 alimentées par l'intermédiaire du collecteur 9.This cage also carries, externally mounted, a collector 9 intended to take the current on the on 10 'brushes. The cage 8 also carries, externally mounted, two flywheels 10 and 11 coaxial with the two half-shafts 4 and 5 and each located on one side of this cage, these flywheels being traversed by the aforementioned half-axes mounted free in rotation. The flywheels 10 and 11 carry a series of coils 12 supplied via the collector 9.

Le mécanisme d'accouplement comprend en outre deux volants d'entraînement 13 et 14 en matière ferromagnétique. Le volant 13 est monté solidairement sur le demi-arbre 4 tandis que le volant 14 est monté solidairement sur le demi-arbre 5. Ces volants sont parallèles aux volants 10 et 11 munis de bobines 12 et proches de ces derniers.The coupling mechanism further comprises two drive wheels 13 and 14 made of ferromagnetic material. The flywheel 13 is mounted integrally on the half-shaft 4 while the flywheel 14 is mounted integrally on the half-shaft 5. These flywheels are parallel to the flywheels 10 and 11 provided with coils 12 and close to the latter.

Le bâti 1 porte en outre des bobines de freinage 15 et des bobines d'inversion de marche 16.The frame 1 also carries braking coils 15 and reversing coils 16.

La fixation des volants 13 et 14 aux demi-arbres correspondants s'effectue au moyen des flasques cannelés 17.The flywheels 13 and 14 are fixed to the corresponding half-shafts by means of fluted flanges 17.

Les balais 10' sont montés dans un support qui porte en même temps les bobines d'inversion de marche 16.The brushes 10 'are mounted in a support which at the same time carries the reversing coils 16.

Les volants 10, 11 porte-bobines présentent, sur leur surface qui fait face aux volants d'entraînement, des évidements ou rainures, par exemple, en forme de couronne circulaire, dans lesquels sont logées les bobines 12.The flywheels 10, 11 reel holders have, on their surface which faces the drive flywheels, recesses or grooves, for example, in the form of a circular crown, in which the reels 12 are housed.

Avec la constitution ainsi décrite, et si le demi-arbre 5 est celui qui est relié au moteur d'entraînement, la rotation de ce demi-arbre provoquera la rotation du volant 14 et de la cage 8 dans laquelle sont logés les planétaires et satellites, sans que le demi-arbre 4 ne soit entraîné. Dès que les bobines 12 des volants 10 et 11 sont excitées, la rotation du volant 10 avec ses bobines excitées, provoquera la rotation du volant 13 et, avec elle, celle du demi-arbre 4. Par excitation des bobines 16, on obtient le freinage des volants 10 et 11, en produisant ainsi l'inversion de marche à l'aide de l'ensemble de planétaires et satellites.With the constitution thus described, and if the half-shaft 5 is that which is connected to the drive motor, the rotation of this half-shaft will cause the rotation of the flywheel 14 and of the cage 8 in which the planets and satellites are housed , without the half-shaft 4 being driven. As soon as the coils 12 of the flywheels 10 and 11 are excited, the rotation of the flywheel 10 with its excited coils, will cause the rotation of the flywheel 13 and, with it, that of the half-shaft 4. By excitation of the coils 16, the braking of the steering wheels 10 and 11, thereby producing the reversal of motion using the set of planets and satellites.

La vue éclatée de la figure 2 représente une forme possible de réalisation, sur laquelle les éléments identiques sont désignés par les mêmes numéros de référence.The exploded view of FIG. 2 represents a possible embodiment, in which the identical elements are designated by the same reference numbers.

Les volants 10 et 11 présentent un arbre tubulaire 18 traversé axialement par les demi-arbres correspondants avec interposition de roulements 19. Sur cette vue éclatée, on peut remarquer l'évidement torique des volants 10 et 11 et la configuration analogue adoptée pour l'ensemble des bobines 12. Les arbres tubulaires 18 traversent les volants 13 et 14, avec montage au moyen de roulements 20, de bagues de retenue de graisse 21 et d'un écrou de fixation 22.The flywheels 10 and 11 have a tubular shaft 18 axially traversed by the corresponding half-shafts with the interposition of bearings 19. In this exploded view, we can note the toroidal recess of the flywheels 10 and 11 and the similar configuration adopted for the assembly coils 12. The tubular shafts 18 pass through the flywheels 13 and 14, with mounting by means of bearings 20, grease retaining rings 21 and a fixing nut 22.

Sur cette figure 2, on remarque également une forme particulière de la cage ou du corps porte-satellites 8 sur lequel est monté le collecteur de prise de courant 9.In this FIG. 2, there is also a particular shape of the cage or of the planet carrier body 8 on which the socket-outlet collector 9 is mounted.

Etant donné que, dans le mécanisme selon l'invention, la transmission se produit à l'aide d'un champ magnétique, en faisant varier l'intensité de ce champ, soit par le nombre de bobines excitées, soit par l'intensité d'excitation de celles-ci, on peut faire varier la force d'entraînement en partant de zéro jusqu'à la rendre égale à celle de l'arbre menant, dans l'utilisation de ce mécanisme comme embrayage. Ce dispositif apporte, entre autres, l'énorme avantage de permettre d'embrayer en tirant parti du couple maximum du moteur(grande vitesse de rotation de l'arbre menant) sans risque pour l'intégrité du dispositif, en résolvant ainsi le problème évoqué au début du présent mémoire.Since, in the mechanism according to the invention, transmission occurs using a magnetic field, by varying the intensity of this field, either by the number of excited coils, or by the intensity d 'excitation of these, we can vary the driving force from zero to make it equal to that of the drive shaft, in the use of this mechanism as a clutch. This device brings, among other things, the enormous advantage of making it possible to engage by taking advantage of the maximum torque of the engine (high speed of rotation of the driving shaft) without risk for the integrity of the device, thereby solving the problem mentioned. at the beginning of this brief.

Etant donné que l'entraînement de l'un à l'autre des demi-arbres, menant et mené, se produit à l'aide de l'action du champ magnétique d'intensité variable précité, pour une valeur donnée du nombre de tours de l'arbre menant, on obtient sur l'arbre n-êné le nombre de tours désiré, par un simple réglage de l'intensité du flux magnétique, ce qui permet d'utiliser le mécanisme comme variateur de vitesse.Since the entrainment of one of the half-trees, leading and led, occurs by means of the action of the magnetic field of variable intensity mentioned above, for a given value of the number of turns of the driving shaft, the desired number of turns is obtained on the same shaft by a simple adjustment of the intensity of the magnetic flux, which makes it possible to use the mechanism as speed variator.

Il ressort de ce qui a été exposé plus haut que le mécanisme remplit les conditions d'un convertisseur de couple classique, avec l'avantage sur celui-ci de la simplicité et du plus faible coût.It appears from what has been explained above that the mechanism fulfills the conditions of a conventional torque converter, with the advantage over the latter of simplicity and lower cost.

En outre, le mécanisme selon l'invention peut être utilisé comme régulateur de vitesse. Cette qualité présente sa plus grande application dans le domaine automobile, en particulier dans le cas de l'utilisation d'une automobile dans les zones à vitesse limitée. Lorsque l'aiguille du tachymètre se place dans la position choisie à l'avance, un mécanisme électronique peut agir sur les bobines électromagnétiques du ralentisseur en augmentant l'action de celui-ci en fonction de l'excursion décrite par cette aiguille.In addition, the mechanism according to the invention can be used as a cruise control. This quality has its greatest application in the automotive field, in particular in the case of the use of an automobile in areas with limited speed. When the tachometer needle is placed in the position chosen in advance, an electronic mechanism can act on the electromagnetic coils of the retarder by increasing the action of the latter as a function of the excursion described by this needle.

L'utilisation du mécanisme selon l'invention en tant que ralentisseur est obtenue au moyen des bobines électriques 15 prévues pour le freinage électromagnétique des arbres de transmission.The use of the mechanism according to the invention as a retarder is obtained by means of the electric coils 15 provided for the electromagnetic braking of the transmission shafts.

Finalement le mécanisme selon l'invention peut être utilisé comme inverseur de marche puisque les bobines 16 sont fixées au bâti 1 et que, lorsque ces dernières reçoivent du courant, elles freinent, grâce au champ magnétique créé, le rotor central constitué par les volants 10 et 11 et par la cage 8 des planétaires et satellites, en déterminant de cette façon l'inversion de marche sur le demi-arbre mené, par l'intermédiaire desdits planétaires et satellites.Finally, the mechanism according to the invention can be used as a reverser since the coils 16 are fixed to the frame 1 and that, when the latter receive current, they brake, thanks to the magnetic field created, the central rotor constituted by the flywheels 10 and 11 and by the cage 8 of the planetaries and satellites, by determining in this way the reversal of operation on the driven half-shaft, by means of said planetaries and satellites.

On peut prévoir que le volant 10 présente un rayon plus grand,qui permette d'accoupler une série d'éléments de friction qui sont constamment pressés par des ressorts contre le volant d'entraînement 13, de manière que, lorsque les deux arbres tournent à la même vitesse, l'embrayage se comporte comme un embrayage mécanique, qui peut être éliminé au moyen des bobines électriques correspondantes tandis que son bord périphérique sert de disque pour au moins un étrier qui agit comme disque de frein et que l'on utilise dans le cas de l'inversion de marche.Provision can be made for the flywheel 10 to have a larger radius, which makes it possible to couple a series of friction elements which are constantly pressed by springs. against the drive wheel 13, so that when the two shafts rotate at the same speed, the clutch behaves like a mechanical clutch, which can be eliminated by means of the corresponding electric coils while its peripheral edge serves as a disc for at least one caliper which acts as a brake disc and which is used in the case of reverse gear.

Bien entendu, diverses modifications pourront être apportées au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention.Of course, various modifications may be made to the device which has just been described only by way of nonlimiting example without departing from the scope of the invention.
